Can't Save My Blocks or Programs

Below is a response from LEGO Education Support to an intermitenet problem where you cannot save your “MyBlocks” or you cannot save your programs to the default path.

"With any version of PC go to the settings.ini file. Make sure the students have full control of this file path. The default location is My Documents\LEGO Creations\Mindstorms Projects\Profiles\Default\settings.ini and delete the file. When the LEGO Mindstorms NXT program starts again, it will rebuild that file."
